This is the circuitry of a programmable remote control.
The pins in the lower part of the picture are connected to a 2-lines back-lighted alphanumeric LCD; as the remote control just costs,brand new, 8 Euros, I'd like to figure out if and how I can access and drive the display to use it with an Arduino.
The pins in upper part of picture are clearly available for external access, but.... how to figure out their use (if possible)?
